I have discovered that when using the scph1001 bios I get lower fps than using the PAL scph7502 bios, at least when playing FF8. I get roughly the same fps whith the PAL bios as I get when not having a bios at all. And what bios does the FpseCE use when you havent put one in the bios folder?

it is true that the bios does make a slight difference in speed. on the ipod touch 2g psx4iphone ran best with the 7502 bios by a few frames. i haven't tried it on fpsece yet because i didn't really feel the need to. on the ipod touch 2g i only got about 20-30 frames with frameskip it was nothing near playable so i gave up on it. but i think the frames will be worth it here so i'll do a bit of testing.
